I’m continued to be amazed by E02. For the first time today I’m pairing it with Z1R, and boy oh boy, it takes the Z1R to another level. Overall sound becomes fuller and a lot more lively! Treble, which to me is at borderline sibilance, has a lot more weight and this alleviates the tendency to be sibilant. However, this doesn’t mean that treble becomes muted, on the contrary, it retains the energy while having more extension. Bass is more analogue sounding with just the right amount of decay, and most importantly, mids are more forward (perhaps due to improvement in treble area).
I do believe now Z1R is benefiting a lot from a high powered source. E02 is a much much better pairing than 1Z and definitely becomes my go to source for Z1R. Very very happy camper here. Just wish it has the battery life of 1Z, but I guess we can’t have it all
The n6ii was my favorite source for Z1R too. Have you tried the E01?
